[vtkusers] Segmentation Fault: vtkXOpenGLRenderWindow::MakeCurrent

[Ken Martin]

Also in VTK 7.0 there were cases where when working with multiple windows
or removing actors/mappers/textures from a live window could cause this
type of error. If you have just one window and are not removing
actors/mappers/textures from it then I'm not sure what it is.
